I was able to rebuild my water pump using a 17104.83 Omix-Ada water pump bearing and a Gogoal Mechanical 5/8" seal from Amazon. You will have to reuse your pump vane assembly so make sure the back surface is stoned flat where the mechanical seal will ride. I was not able to find the little sap wire clip so I just used part of a cotter key. Since they are no longer remanufactured by Cardone I thought this might help out.
